LOCK MECHANHSM.

Specification of Letters Patent.

Patented Feb. 20, 1906.

To all whom it may concern:

Be it known that we, CHARLES J. CALEY and HENRY G. VOIGHT, citizens of the United States, residing at New Britain, Connecticut, have invented certain new and useiul Improvements in Look Mechanism, of which the following is a full, clear, and exact descripmechanism. Fig. 5 is a tion.

Our invention relates to improvements in lock mechanism.

The object of the invention is to provide a simple lock mechanism which may be readily applied to a door of any thickness (within reasonable limits) without disturbing the alinement or adjustment of the parts.

hThe invention is particularly directed to t at operated from the inside of the door by a thumb-piece and operated from the exterior only by a key. For this purpose the bolt and bolt-actuating mechanism are all carried by a frame-platr located at the inner edge of the door, while the cylinder-lock is carried by another frameplate located on the outside of the door, said plates being provided vwith mutually cooperable members for properly positioning the parts and also securely attached to the door by screws accessible from the inside frame-plate The cylinder-lock is so constructed as to be readily applied or removed and so as to provide a centralizing device for the key.

The principles of the invention are illustrated in the accompanying single sheet of drawings.

Figure 1 is a plan view and horizontal section of mechanism involving the improvements of our invention. Fig. 2 is a view of the inside of the inner frame-plate, together with the latch-bolt and operating mechanism. Fig. 3 is a front view of the lock mechanism. Fig. 4 is an end view of the cylinder-lock vertical projection of the outer frame-plate.

1 is the nnerframe-plate.

2 is a rojecting portion thereon forming an end p ate adapted to stand over the edge of the door.

3 is a latch-bolt suitably pivoted and normally pressed outward, as is customary.

. 4 is the latch-slide, provided with suitable guideways and stops.

5 is the inner actuating member or thumbinner type of lock in which the latch or bolt is piece, provided with suitable bearings in the ame-plate.

6 is the roll-back, operated by the thumbpiece 5 and adapted to coact with the slide 4.

7 represents a split ring seated in a groove and adapted to hold the thumb-piece in position.

8 is the outer frame-plate.

9 is the body of a cylinder-lock containing suitable pins, &c.

10 is a plug member of the cylinder-lock adapted to be turned relative to the body when the proper key is inserted.

11 is an annular plate provided with an opening with walls converging toward the plug 10.

12 12 are webs or projections carried by this plate 11 and adapted to be seated in grooves or recesses correspondingly formed in the outer frame-plate 8 for preventing the parts from rotating relatively to one another.

13 is a screw-threaded portion on the body of the cylinder-lock which is seated in a correspondingly-threaded portion of a tubular portion extending rearwardly from the plate 11.

15 15 body 9. v

16 16 are set-screws coacting'with tapped holes in lugs 15 15 and adapted to be adjusted so as to press against the inner face of the are lugs projecting from the cylinderouter frame-plate 8 and draw the plate 11 securely into position, as shown in Fig. 1.

By this construction we are enabled to manufacture a suitable lock and secure it to the outer frame-plate in an economical and satisfactory manner and so that the parts cannot accidently become displaced after they are once assembled.

' 17 is a shank suitably mounted on the extension of the shank of the inner knob or thumbiece. therewit and adapted to coact with the latch-slide 4.

19 is a keeper-plate suitably secured to the inner frame-plate 1 and adapted to hold the roll-back 18 and its shank 17 in place.

20 is a spindle carried by the plug 10 and projecting into a correspondinglyshaped o ening in the shank 17. The turning of the plhg 10 therefore by means of a key will rotate the shank 17 and roll-back 18 and retract the slide 4 and latch-bolt 3.

18 is a roll-back rotatable 5 the parts together.

IS with from the exterior.

21 21 represent tubular projections carried by the inner frame-plate 1.

22 22 are posts carried by the outer frameplate 8 and adapted to fit into the tubular 5 members 21 21 and properly aline and posi tion the parts.

23 represents one of a pair of screws adapted to be inserted through the inner frameouter frame-plates adapted to be secured to the opposite sides of a door, latch-o erating mechanism carried by one of sai frameplates, including two roll-backs, and a thumb-piece connected to one roll-back a 2 5 cylinder-lock mechanism carried by the.op-

posite framelate, means of connection between sald cy inder-lock mechanism and the other roll-back and a guard-plate on the exterior of said last-mentioned frame-plate and 0 having an opening with walls converging concentrically to the plug of said cylinder-lock.

2. In a lock mechanism, the combination of an inner frame plate, latch operating ,mechanism carried thereby, an outer frame- 3 5 plate, a cylinder-lock body having a screw threaded portion, a plug, means of connection between said plug and said latch-operating mechanism a member mounted in said outer frame-plate having a screw-threaded 4o portion engaging with the screw-threaded portion of sai cylinder-body, means for preventing rotation of said member in said outer frame-plate, and means for clamping said cylinde -body and member in-place in said 4 5 outer frame-plate.

3. In a lock mechanism, the combination of inner and outer frame-plates, an operatingslide for the latch-bolt carried by the inner frame-plate, a thumb-pliece mounted in said inner frame-plate and aving a roll-back for cooperation with said slide, a cylinder-lock carried by said outer frame-plate in-line with said thumb-piece, a shank and roll-back in line' therewith adapted to coact with said slide, a s indle connection between said cylinder-locii and said shank, and means for alining and positioning said inner and outer frame-plates.

4. In a lock mechanism, inner and outer frame-plates adapted to the opposite sides of a door, an end plate carried by one of said frame plates, a latch bolt operable therethrough, a slide carried by one of said frameplates, a thumb-piece and roll-back for cooperating therewith, a cylinder-lock carried by the outer frame-plate, a spindle rojecting therefrom in line withsaid thum -piece, a roll-back controlled thereby inde endent of said first-mentioned roll-back an for cooperating with said latch-slide, and means for clam ing said frame-plates in place.

5. En a lock mechanism, the combination of inner and outer frame-plates, a latch-bolt and operating-slide carried by one of said framelates, a thumb-piece carried by said inner rame-plate-for operating said latchslide, a cylinder-lock mechanism carried by the outer frame-plate with connections for operating said latch-slide, tubular members projecting from said inner frame-plate near the edge thereof, posts corresponding thereto and projecting from'the outer frame-plate, screws cooperating therewith for drawing said frame-plates together, and an independent screw for drawing said frame-plates together and located at the rear of sa1d thumbpiece and cylinder-lock.
